Key Features

RC522 chip introduction: MF RC522 is applied to 13.56 MHz contactless communication high integration of reading and writing card chip, is NXP in "three table" application offering a low voltage, low cost, small volume, non-contact, speaking, reading and writing card chip, is intelligent instrument and portable handheld equipment research and development is a better choice. MF RC522 use advanced modulation and demodulation concept, fully integrated the 13.56 MHz down all types of passive contactless communication mode and agreement. Support 14443 a compatible transponder signal. Digital parts processing ISO14443A frame and error detection. In addition, also support the rapid CRYPTO1 encryption algorithm, it is used for verification MIFARE series products. MFRC522 support MIFARE series more high-speed contactless communication, two-way data transmission rate is as high as 424 kbit/s. As 13.56 MHz high integration, speaking, reading and writing card series chips the new members of the family, MF RC522 and MF RC500 and MF RC530 have some similarities, but also have many characteristics and differences.It and communication between host the SPI mode, which is beneficial to reduce the attachment, and narrow PCB volume, lower the cost.

RFID module introduction:

MF522 - AN module by Philips MFRC522 original chip design card read circuit, easy to use, low cost, suitable for equipment development, card reader development advanced application user, the need for radio frequency card terminal design/production of users. This module can be directly into all kinds of card reader mould. Module USES a voltage of 3.3 V, through the SPI interface simple lines can directly with the user any CPU motherboard phase connection communication, you can ensure that the module is stable and reliable work, card read distance;
